Don't Go Into Dark Magic

One day Ness was bored, so he decided to leave the Smash Mansion and head out into the haunted forest. When he came back, he looked... slightly different. 'He' wasn't exactly a boy... anymore. What happened?
In the forest, the young pSI teenaged boy bumped into Toadette, who was practicing magic with Dry Bowser. Toadette didn't realize that the skeletal reptile was teaching her dark magic, so she inadvertently turned Ness into a girl. Of course, being that Ness already looked like a girl, no one could tell the difference. With that said, only one person noticed... and it was Olimar.
Seeing Ness acting more polite triggered a cue that something was not right, so Olimar went to the exact same haunted woods that the PSI kid was. He bumped into Toadette, who was having some tea with some woodland creatures as Dry Bowser was using his dark magic to conjure up a camp site. Olimar asked what was going on, and Toadette explained it was magic. Olimar was deliberately mean in demanding Ness to return to normal, which caused Toadette to cry.
Dry Bowser did not like this, and used his dark magic to turn Olimar into a carrot, with all his Pikmin following their leader and gasping as they spotted the carrot that had Olimar's face on it, with a blue bunny snatching it up and eating it, the Pikmin all fainting and dying in shock.
And that is why you do not dabble in the dark arts.
